This invention relates to improvements in powder distributing devices, and pertains.

particularly to an improved blower vfor in-' secticidal powders.

The primary object of the present invention is to provide an improved bellows operv. ated powderfblower or distributor having novel means for introducing air into the f powder receptacle from which the'powdery is ejected.

Another vobject ofthe invention is,v to pro-l vide Ia novel means for diffusing the air .through the powder so thatthe powder will be expelled from the receptacle in the form 1570i a light dust. l,

two substantially heart shaped Hat bodies 2 and 3 each of which is provided at its larger Arelative to the portionQ7 which latter portion may be referred to.. as theiixed portion, Yhas connection at vitsreduced end 9 with-aseparate neck portion 10, through the mediumof ar hingell.. Thisv'neckv portion 10 -ofthe side of the bellows also has its inner face provided with a ylongitudinally extendingigroove" 12 which coincides with .the groove8 to forman air passagel `from the interior of the bellows `to the powder receptacle, kabout to be de-k .scribed.A The forward ends' ofthe'two neck portions 7 and 1.0 of the bellows sidesare re- Uducedas indicated at 14. l The movable. portion 'i3 ofthe bellowsl is normally maintained spaced from the fixed portion 2 by a springV 15 and this portion isalso'provided with*4 an `air inlet aperature 16 which is coveredfbya leather'flap valve17. l

The neckoi;l the, bellows, whichis made up of the portions 7 and 10, is connected with a kpowder receptacle f which is lindicated as a whole by the numeral 18, through the medium of thesleeve 19, one end of which receives the reduced portionk 14 in the manner illusy. trated. The receptacle 18 is made up-of the two portions 20 and 21 which are telescopically oined as illustrated, portions-'of the abuttingfaces of these portions being threaded as indicated at 22 to establish atight connection The portion20 ofthe receptacle, whichv portion of'which eXtendsinto thesleeve 19 may be referredto as the inner portion, has 3' thesleeve 179 joined `to the inner end wall`23 thereof as. illustrated and extending laterally lfrom theY forward end of the sleeve 19 is an angularly shaped tube 211, the free end of one and passes outwardly over the adjacent end 23 of the receptacle portion 20, while the other portion of the tube extends forwardly longitudinally of and against the side wall of the portion 20 and tapers off to a point at its forward end as illustrated. The portions of the end and side walls of the inner receptacle portion 20, which are covered by the angular tube 24, are provided with aperturesv 25 so that communication is established between the interior of the receptacle 18 and the sleeve 19 through these apertures and through the tube. It will be seen that when air is forced from the bellows into the sleeve 19 the apertures in the end wall 23 of the receptacle will permit blasts of air to be directed forwardly and longitudinally through the receptacle. while the apertures through the side wall will introduce cross blasts of air so that a thorough agitation of the powdery contents of the receptacle will be obtained.

The forward end of the removable portion 21 of the receptacle 18 is covered by an apertured wall 26 which serves as a baiiie plate and covering this apertured wall is a. funnel shaped outlet 27 which empties into a. short substantially cone shaped discharge nozzle 28, the base portion of which is provided with screw threads 29 for the purpose to be hereinafter described.

The short nozzle 28 which is integrally connected with the reduced forward end 27 of the receptac-le may be employed for distributing powder over plants or other bodies which are located close at hand. When the powder is to be distributed on objects which are some distance away from the user of the blower there is provided a long extension nozzle 30 which is of a diameter at one end to receive the base portion of the nozzle 28 and which is interiorly threaded at this end for engagement With the threads 29. This has the short nozzle 28 inserted thereinto in the manner shown so that powder may be blown from the receptacle therethrough onto vines or plants which would be out of reach when using the short nozzle 28.

From the foregoing description it will be readily seen that by the use of a powder blower constructed in accordance with the present invention the air ejected from the bellows 1 will be introduced into the powder receptacle 18 in such a manner as to thoroughly whip up or agitate the powder and1 of the apertured baille plate over the outlet of the receptacle, the powder is caused to leave the blower in a thoroughly dispersed condition or, in other words, in the form of a dust cloud rather than with the particles in closely related formation as is the case with ordinary blowers.

It will also be seen that the receptacle may be easily and quickly filled by removing the outer section 21 from the end of the inner section 20, thus leaving the entire forward end of the inner section open so that the powder may be readily dumped thereinto. It will also be seen that the disposition of the air inlet apertures 25 to one side of the vlongitudinal center of the receptacle has a further advantage in that the powder, when being dumped into the receptacle, will not be apt to pass into and iill the sleeve. 19 as it would do if the apertures were located in the center of the bottom 23 over the forward end of the sleeve.

By tapering the longitudinally directed portion of the tub-e 24, from the rear to the forward end thereof in the manner shown,

the possibility of powder getting into the tube -and clogging it is avoided and al much more effective transverse blast of air into the receptacle is obtained, for the thorough agitation of, and mixture of the air with, the` powder results.
